This round 5V LED matrix lamp Kit offers a really bright light, which is compact and easy to mount. The unit is supplied with 9 white super flux LEDs, which collectively output around 16,000 mCd. The unit incorporates current limit resistors, allowing it to be run from a 5V supply or 3 x AA batteries can be used (3 new batteries will last for around 5 hours).
The kit makes a nice desk lamp when powered from our micro USB power supply (used to charge many phones, tablets and e-readers) which can be done by using our micro USB break out board.
